- EGG BEATER.

No. 104,174. Patented June 14,1870.

new glitter new amine Letters Patent No. 104,174,, dated June 14, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 11 may concern 7 Be it known that we, THOMAS MARSH and James BER}TEY, of Pawtucket, in the county of Providence,-in the State of RhodeIsland, have invented a new and useful Improvement in Egg-Beaters, of which the following is a specification.

The object of this invention is to construct an egg-beater with two revolving heaters, in such manner as will overcome objections that existed previous to this invention.

It has been found that where a single revolving beater has been used, the rapid revolutions of which, in order to breakup and entirely destroy'the tenacity with which the albumen of the egg is so intimately connected, will, by its centrifugal force, throw the substance of the egg'to the inside of the dish containing the egg and the beater, and away from the action of the beater, and without doing what was intended it should do, and when two boaters have been used, they revolve in such direction that the motion of the two is unlike what is hereafter described as the invention; nordo such heaters produce the effect intended.

This invention consists in the construction of the parts, and their arrangement, with relation to each.

other, so as to produce the client desired.

In the drawing- Figure 1 is an upright sectional view of the beater,

' and Figure 2 is a transverse view of the same.

Figure 3 is a modification of fig. 1, and

Figure4, a transverse view of fig. 3.

A is a metal frame that supports the operating parts, and at its upper end, for convenience of bolding, has a loop-handle, A.

B is the main driving gear-wheel, revolving on an axis made fast to frame A at g, and is made to revolve by the crank-handle B.

The gear-wheel B gears into pini'ons b b, that revolve with their axles in cross-bar a at the bottom of frame A.

These piuious b b have their teeth inclined with relation to their axes, and so asto gear into and freely work with the teeth on the wheel B, and overcome the difference caused by the axis of rotation of wheels of the center of frame A, and extends below the lower ends of the heaters (Z (Z to a crossabar, e end is made secure thereto at point e.

The heaters d d are made of sheet metal that will not rust, bent at their bottom ends to-the proper circle, the two upper ends made fast to the under side of the yoke or cr'oss 1)ieces b b, while their sides are straight from the ends of the cross-pieces l) b to the point where the semicircle commences that forms the bottom of the beater, but gradually grow wider from their top ends, or where they are fast to the yoke, to the point where they bend to form the half-circle at their bottom ends. 7

'Ihesc heaters turn freely on pivot-pins d d'at their bottom-ends, and revolve with piuions lab.

Pivot-pins d (1 pass through the bottom cross bar a, and are made fast thereto, and keep the bottom ends of the heaters in place, and allow them to turn on these pivots freely.

In order to strengthen the sides of the heaters, and secure them from bending or. springing, a half-circle brace, f, is placed near to their upper ends and be tween the sides, and made fast thereto.

To operate the beaterygear-whecl B may be turned in either direction, and will give a rapid revolution to the piuious b b and boaters d d, and in such direction as to prevent the substance of the egg from being thrown away from the action of the heaters, for while both heaters revolve in the same direction, yet the sides of the boaters adjacent to each other, as they approach, are traveling in opposite directions, which has the tendency and does act to separate the substance of the egg much quicker and more thorough than is done by either a single heater or by two. or more heaters thatrevolve in a different manner .fromthat herein described. I

This motion is produced upon the heaters by the use of the single driving gear-wheel gearing into and revolving the two pinions and heaters; but it is we dent that other arrangements of gear-wheels will produce the same effect, as, for instance, wheerB may gear into and revolve a pinion upon a shaft where another pinion is attached, the sccond pinion acting as the driving-wheel to the pinions that'are attached to the heaters, and the effect will be the same, as is seen in the modification represented in figs. 3 and 4, where a gear-wheel or pinion, O, is made by wheel B to turn a shaft, 0, which freely revolves in proper hearings in frame A and bottom cross-bar c, and has pinion b'" attached to and revolve with it andgive revolution to the pinions b b and to the heaters 11 d, but we greatly prefer the construction and arrangement of gearwheels as represented in figs. 1 and 2, to give the do; scribed motion to the heaters, for, by such. arrange},

merit, a less number of gear-wheels is used, and,- as

a consequence, reduces the frietion and saves the power that would be used to overcome the extra amount of friction.

We do not broadly claim for the gear that revolves the heaters, nor the heaters, as gear-wheels have been used for revolving the heaters, previous to our invenlion.

Having thus described our invention,

What we 'elaim, and desire to secure by Letters Patent, is-

v 1. The combination, in an egg-beater, of the gearwheel B, pinions b b, and heaters d d, when the parts are constructed to operate in the manner described.

2. The combination of the gear-wheels B O b" and b b with the heaters d d,-constructed and arranged to operate in the manner described.

3. The egg-beater,constructed as above described.
